Interaction of Biased Electrodes and Plasmas: Sheaths, Double Layers and Fireballs
Scott D. Baalrud, Brett Scheiner, Benjamin Yee +2
Biased electrodes are common components of plasma sources and diagnostics. The plasma-electrode interaction is mediated by an intervening sheath structure that influences propertie…
Theory and simulation of anode spots in low pressure plasmas
Brett Scheiner, Edward Barnat, Scott Baalrud +2
When electrodes are biased above the plasma potential, electrons accelerated through the associated electron sheath can dramatically increase the ionization rate of neutrals near t…
Particle-in-cell study of the ion-to-electron sheath transition
Brett Scheiner, Scott D. Baalrud, Matthew M. Hopkins +2
The form of a sheath near a small electrode, with bias changing from below to above the plasma potential is studied using 2D particle-in-cell (PIC) simulations. Five cases are stud…
Theory of the Electron Sheath and Presheath
Brett Scheiner, Scott D. Baalrud, Benjamin T. Yee +2
Electron sheaths are commonly found near Langmuir probes collecting the electron saturation current. The common assumption is that the probe collects the random flux of electrons i…
Electron Preheaths: The Outsized Influence of Positive Boundaries on Plasmas
Benjamin T. Yee, Brett Scheiner, Scott D. Baalrud +2
Electron sheaths form near the surface of objects biased more positive than the plasma potential, such as in the electron saturation region of a Langmuir probe trace. Generally, th…
Extensions and Applications of the Bohm Criterion
Scott D. Baalrud, Brett Scheiner, Benjamin Yee +2
The generalized Bohm criterion is revisited in the context of incorporating kinetic effects of the electron and ion distribution functions into the theory. The underlying assumptio…
